How Does a Home Backup Generator Work?

A Generac home backup generator senses a power outage, turns on automatically, and delivers backup power to your home. It will run until utility power returns - whether that's two hours or two weeks.

1 Utility Power Is Lost

Perhaps it's a storm. Maybe it's an equipment failure. In any case, the electricity you depend on is suddenly gone.

2 Your Generac Generator Senses A Problem

Within seconds, your generator prepares to restore your home's power.

3 The Generator Turns On Automatically - Whether You’re Home Or Away

Within a few seconds, it is up to speed and generating electricity.

4 Your Electricity Is Restored

The automatic transfer switch sends generator power to your home. And it will continue until utility power returns.

After 17 years of living the "sump pump worry" life, I can sleep better at night knowing we have a Generac Generator in place now. Adams Electric was great to work with. Don came out and explained the details very well. He used his ipad program to walk through specifics and figure out what size generator we would need based on our requirements. On the day of the install, the techs came out and did a great job. They spent time walking through the details when they were done as well as making sure that all of my needs were met when the back up generator was running. They left nothing behind but quality workmanship. If you are reading this and wondering whether you should have it done, I would encourage you to make it happen. I wish I would have done it 15 years ago. Thanks again Adams Electric for a job well done! Cheers!! MuskyU Silver Lake, WI
